I have recently put a new instal of windows 7 on my PC. One thing that is strange is that the network card won't log in to the intenet straight away. This strangly enough happened in exactly the same way last year after a re-install.

I can get it going again, by 'randomly' using the advance settings. Which dosn't make muh sense. There is no pattern to why it works (after random tweaking) . I thought it might be the power management. It is working now as I am here talking to you.

It makes no sense that this device should not work after reboot.

The driver version is 7.6.820.2009,

Could there be a bug, or maybe the firewall is not accepting it.

There are settings such as 'Jumbo flame' 'Flow control'.. Means nothing to me, and there is no doumentation to explain what this does.

what are the actual settings to make this device work without me having to do anything else?

The first thing I would try is downloading drivers for the Realtek PCie GBE Family Controller saving them to your system.Next I would uninstall the device, reboot and when the Realtek PCie GBE Family Controller is found use the drivers you downloaded.

Yes it could be bad, however I would think that is not the case because you can make it work.

Open up Network and Sharing Center. You can find this by going to Start then typing Network and Sharing Center into the search box.

In the left window pane click Change adapter settings.

You will see all of your network adapters here which include the Ethernet and Wireless adapters.

Depending on what you are trying to fix, choose the appropriate adapter. Usually, Local Area Connection is your Ethernet adapter and Wireless Network Connection is your Wi-Fi adapter. Although, these might be named differently the default names are Local Area Connection and Wireless Network Connection.

Disable the adapter that is having issues with internet connectivity either by right clicking the adapter and selecting disable, or double clicking the adapter and choosing the disable button.

Re-enable the adapter by double clicking it. You can also re-enable it by right clicking on the adapter icon and selecting Enable.

Try reset the Bios default, then look for the card in the Bios and see what state that is.If enabled by default, try disable that, save exit.Reboot to the Windows confirm the device not in the devices manager.Next repeat the process again by enabling the device in Bios and save exit.Reboot to the Windows and look for the device in the Device manager again.

Reintall the latest mobo chipset driver and reboot after that, hope the new chipset driver can help with the onboard devices integrity to work better together.

Next to do is check on the cable connection and the Lan card connection as well.Oxidation may have caused the intermittent no work to the internet.Maybe use the other working cable and clean the LAN card connection pins with a cotton stick carefully.

Hope this can get you the reliable internet connection again without manually enable that in the Windows periodically.
